Logic Diagram
DESCRIPTION:
Maxwell Technologies’s 124 independent, high gain, internally
frequency compensated operational amplifiers feature a
greater than 100 krad (Si) total dose tolerance, depending
upon space mission. Using Maxwell’s radiation-hardened
Rad-Pak® packaging technology, the 124 is designed specifi-
cally to operate from a single power supply over a wide range
of voltages. The 124 also features operation from split power
supplies, and the low power supply current drain is indepen-
dent of the magnitude of the power supply voltage.
Maxwell Technologies' patented RAD-PAK® packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
age. It eliminates the need for box shielding while providing
the required radiation shielding for a lifetime in orbit or space
mission. In a GEO orbit, RAD-PAK provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.

1. This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base
junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this
diode action, there is also lateral NPN parasitic transistor action on the IC chip. This transistor action can cause the output
voltages of the op amps to go to the V+ voltage level (or to ground for a large overdrive) for the time duration that an input is
driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative,
again returns to a value greater than -0.3V (at 25°C).
2. Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to
ground, the maximum output current is approximately 40 mA independent of the magnitude of V+. At values of supply voltage
in excess of +15V, continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction.
Destructive dissipation can result from simultaneous shorts on all amplifiers.
